"Earl: I looked at the pcb layout, you must have some 0.1uF caps to decouple the 5V supply, located
right at the chip power and ground pins. Also a 10uF cap at least on the 5V. A ground plane helps a lot, too.
CPU's will not work without these…"
"This sounds like a parallel to model rocketry legislation. After 911, the gov freaked, and instituted tough regs on
rocket engines and even fireworks. They forbid transport by train, which caused many cities to not be able to get fireworks for the…"
"This says it does. But I think they are a lot of trouble. Dean has said they don't work
in the rain.
Since the infrared environment is not affected by variation in visible light levels, an airplane equipped with CoPilot could be flown at…"
"Is the Arduino downloader program based on National Instruments software???
You systems is loaded, I see:
-6 DOF IMU
-ultrasonic landing altm
-on screen video
Are you going to make boards and sell them? It appears…"
"I climbed the Sandia mountain, but had to take the tram down. Are you making an ultrasonic altimeter?
Hard to get to work at even 10' I would think. Do you have accel and gyro?
Spin is like C? It looks like greek to me. What do each of the…"
"Interesting, what sensors are you using. How did you program the different cogs? Is Spin difficult? What is
your programming background?
The Alt = 6494, yet it says 55" above the ground, how can that be? BTW, it is descend, to go down!"
"Earl, you may want to try the BaroMod, same cost, but provides a linearized output, 0.25mV per foot, so you
don't have to do nasty math to get a real alt. In hardware, an anti-log amp, the correct voltage is output to your
a/d input. The…"
